ATTACHMENT FOR VEHICLES.

Specification of Letters Patent.

Application filed September 13, 1910.

Patented July 4, 1911.

Serial No. 581,900.

To all whom it may concern:

Be it known that I, CHARLES M. CULBERT- soN, a citizen of the UnitedStates, residing at Carpenter, in the county of Mitchell and State ofIowa, have invented certain new and useful Improvements in Attachmentsfor Vehicles; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful form of bob-sleigh attachmentfor vehicles, and the object is to attach the thills or pole of thevehicle in such a way that the runners will be held in alinement andprevented from rooting into drifts.

With this and other objects in view the invention consists of theconstruction, arrangement and combination of parts described hereinafterand shown in the accompanying drawings which form a part of thisapplication.

Referring to the drawings, Figure 1 represents a perspective view of myattachment applied to a vehicle. Fig. 2 is a detail view of a transverserunner brace. Fig. 3 is a detail view of the shaft cross bar carryingthe thill couplings. Fig. 4 is a detail view of an auxiliary rave-brace.Fig. 5 is another portion of the same, and, Fig. 6 represents a clip forattaching the two transverse bars together.

In the drawing, in which similar reference numerals designatecorresponding parts throughout the several views, 1 is the body of avehicle, 2 is the front axle thereof, and 14 is a sled runnerconstructed in the usual manner, consisting of a runner proper, rave,braces and some form of pivotal bearing for attachment to the end of theaxle. The point 15 of the runner has an opening there through by whichis attached, by some suitable fastening such as a bolt, the end 4 of therave-brace 4:- Adjacent this end isaclip 3, secured to the brace andadapted to form a fastening for the transverse runner-brace 5. The otherend of the rave-brace is provided with bolt holes 6 and a slot 7 for thepurpose of forming a longitudinally adjust-- able fastening with theother section of the brace 8, the end of which 8' is pivotally securedto the axleby the ordinary thill coupling, not shown. It will thus beseen that the draft has been transferred from the thill coupling to thetransverse bar 5 connecting the two runner points. To this bar isattached the shaft cross bar 9, which carries the second set of thillcouplings 9 and 10. The thill coupling 10 is provided with a stem 10extending through the bar and having a threaded end with a nut adaptedto engage the same. This stem is passed through a bolt hole 11 in thebar 5 and a nut being set up upon the end, the two bars are securelyheld together at this point.

On the farther end of the bar 5 a clip 12 is mounted, said clip being aU-shaped memher with threaded ends, having a cross plate 12 adapted toserve as a clamp by screwing down nuts on the threaded stems of 12. Thebar 9 is thus clamped to the bar 5, and, since the stem 10 of the thillcoupling 10 prevents any lateral motion, the two bars constitute to allintents and purposes a single structure. On the thill couplings 9 and 10are secured thills 13 of the usual form, and by forming a number ofspaced bolt holes in the bar 5 it is possible to offset the thills anydesired distance, or to aline them centrally at will. It will be seenthat while the runners 1-1 are still free to oscillate or pivot aboutthe shaft to the degree necessary for passing over rough or unevenground, the attachment of the thills 13 to the points of the runnersprevents the latter from root ing into drifts and holes, and, furtherthe rigid alinement of the runners enforced by the transverse bar attheir points insures perfect tracking and consequent minimum draft.

Although I have shown my attachment adapted to single shafts, it will bereadily recognized that a pole can be used instead with equal success.And further, if so desired the bar 9 may be omit-ted, the thillcouplings being placed directly on the bar 5, which will simplify theconstruction at the expense of the possibility of offsetting the thills.

What I claim is:

In combination, a pair of runners provided with means ontheir rear endsfor pivotal attachment to the front axle of a vehicle, a pair of bracemembers pivotally In testimony whereof I have signed my connected to theforward ends of the runname to this specification-in the presence ofners, brace members adjustably connected to two subscribin witnesses.

D said first brace members and adapted to CHARLES M. CULBERTSON. beconnected to the front axle, clips secured Witnesses: to the first bracemembers, and a transverse G. H. LUBLENs, runner brace secured to theclips. GEO. MGGILLIWAY.
